Our History

Sanchez and Associates was established by Gerardo P. Sanchez in order to provide the Chicagoland area with high-quality surveying. Once established, we began by performing boundary surveys for various real estate companies. We were very fortunate to rapidly grow and expand our services into Transportation, Railroad, and Construction Management since the founding of the company.


Sanchez is a full-service land surveying, bathymetric surveying, and mapping firm headquartered in Chicago, Illinois. We have taken what is known as “land surveying” and extended it from land to air and water through the use of boats and unmanned aerial vehicles. With capabilities such as measuring depths of local bodies of water, to providing detail on tall inaccessible obstructions there is truly nothing we can not handle.


We have built our company on a foundation of hard work, dedication, quality, and professionalism. It all begins with our team at Sanchez, we all have a passion for what we do and strive to provide our clients with deliverables that exceed their expectations. 


Sanchez and Associates is dedicated to being an optimum surveying firm by adding to our team incredibly talented individuals and staying ahead by implementing the latest technologies.
